The atmospheric humidity is varied between 30% and 90% with season in Korea. Thus the influence of humidity on the behavior of wear is important to predict the wear for tools and dies. This paper presents the influence of atmospheric humidity on the wear of carbon steels for the un-lubricated pin-on-disk sliding contact. It was found that the severe wear is dominant at a low humidity and the mild wear is strongly related with the carbon concentration of the steel at a high humidity in this study. The experiments were caned out in a chamber where the humidity was accurately maintained by humidifier. To investigate the relationship, three different carbon steels such as 1020, 1041, and 1045 steels were used.

The reorientations of the atoms by frictional shear deformation at the surface induce cracks at the boundary of the grain. The cracks grow and propagate in regions where the hydrostatic component of stress is least com-pressive because the compressive component restores the cracks by three-dimensional crystallizing π-bondings. The materials, with Luder's band have very small amount of wear at the initial state. It suggests that initial frictional shear deformation be consumed to the formation of the Luder's band. The average wear amounts of the materials increase very steeply as the ø_u, the stress-strain ratio at the ultimate point, decreases.

This study is concerned with hot forging of sintered porous metal ring with inner barrier. It is analyzed by Upper Bound approach for finding the normalized forging pressure at various relative densities and shape factors of the test specimens. Experiments are carried out for sintered porous ring, which were compacted with the powders Fe95 + Cu5, Fe90 + Cu10 and Fe47.5 + Cast iron cutting chip powder 47.5 + Cu5. The specimens are heated in the furnace at 1100℃ and then forged in the preheated die at 200℃. The experimental and the analytical results are compared. Possible explanations for the observed effects are discussed.

불연속 금형을 이용한 정방형 Box-Drawing에서 박판금속의 인발도에 관한 연구

엄태문,오흥국 亞洲大學校 1984 論文集 Vol.7 No.-

This study is concerned with the drawability of sheet metal in square box-drawing with discrete die. A measurable parameter, draw-in, is assumed in order to show the formability of sheet metal in the deep drawing of general shape, of which special case is the drawing tatio in cup drawing. It is through experimental study that optimal size and shape of the blank at given punch size, which are the ones at maximum draw-in, are searched for and the variation of maximum punch load with respect to rolling direction and percentage of reduction are showed. Also the effect on corner-cut of blank and the change of punch force with draw depth are examined. The used die can have two defferent punch sizes (40x40mm, 24x24mm) and change its shape and size. Cold rolled commercial copper and aluminium sheets of 1mm thickness are taken as test material.

ORIENTAL FOUR PHASE CONSTITUTIONS AND MODERN PHYSCIS OF LIFE ENERGIES,Un-gi constitution is the same as four phase one

Great positive has big lungs and weak liver, great negative has strong liver and small lungs, small positive has large spleen and small kidney and small negative has big kidney and small spleen. The formation of DNA at initial conception of human cell is equivalent to atomic bonding while the formation of proteins of the cell growth in a human body is equivalent to molecular bonding. Rotational electro-magnetic wave photo-synthetic starch has no molecular bonding but only gluco pyranoses. The atomic bonding are equivalent to right constitutions while the molecular bondings are equivalent to left constitutions. Five Uns and six Gis are rotational electro-magnetic waves from heaven and land. Jang (lung, liver, spleen, kidney, heart) becomes strong or weak by Uns while Bu(colon, gall, stomach, urinary bladder, small intestine, samcho) becomes strong or weak by Gis. In view of modern physics of life energies four phase constitutions are generated due to more four kinds of life energies than the others. Korean four phase constitutions considered apriority and postreriority at the same time while Chinese Un-Gi constitutions considered only apriority and are the same as the four phase constitutions in apriority. The energy-synthesis from land and heaven is an abnormal phenomenon, that is to say, a kind of energy diseases. The four phase constitutions is very effective for medical curing therefore. The theory of meridian flow in a body is the same as the electric-battery. The constitution are the results from chaotic process.

Stimulation of Blood Flow Needs a Parallel Magnetic Field and Psycho-physics Acupuncture

The conventional model did not take momentum conservation into consideration when the electron absorbs and emits the photons. II-ray provides momentum conservations on any directions of the entering photons, and also the electrons have radial momentum conservations and fully elastic bouncing between two atoms, in the new atom model. Conventional atom model must be criticized on the following four points. (1) Natural motions between positive and negative entities are not circular motions but linear going and returning ones, fur examples sexual motion, tidal motion, day and night etc. Because the radius of hydrogen atom``s electron orbit is the order of 10(-11) m and the radia of the nucleons in the nucleus are the order of 10(-14)m and then the converging π-gamma rays to the nucleus have so great circular momentum, the electron can not have a circular motion. We can say without doubt that any elementary mass particle can have only linear motion, because of the π-rays`` hindrances, near the nucleus. (2) Potential energy generation was neglected when electron changes its orbit from outer one to inner one. The h v is the kinetic energy of the photo-electron. The total energy difference between orbits comprises kinetic and potential energies. (3) The structure of the space must be taken into consideration because the properties of the electron do not change during the transition from outer orbit to inner one even though it produces photon. (4) Total energy conservation law applies to the energy flow between mind and matter because we daily experiences a interconnection between mind and body. Any magnet absorbs n-rays to S pole and sends out the π-rays from N pole. Proton are constructed with the closed n-rays quantum-mechanically. The crystallizing n-bonding makes two π-far infrared rays of one wave length between two protons if two π-rays are supplied to each proton. It is easily done for a π-ray to be absorbed to a proton if there is a parallel magnetic flow to the blood flow because a π-ray advances axially under a magnetic field and a proton looks like a sphere. A axially advancing disk-like π-ray can meet more easily the coming spheres than from the other directions. The blood crystals stimulate the autonomous nerves on the blood vessels during the flow by their mechanical sliding collisions. SM n-ray meridian therapy and SMACN π-ray meridian therapy show the stimulation of blood flow and also combinational experiment between SM π-ray meridian therapy and n-ray psycho-physics acupuncture shows more clearly that magnet is forcing to make π-rays absorbed to the nucleons.

ELECTROMAGNETIC MEANING OF GIBB`S FREE ENERGY, ELECTOLYSIS, CELL REACTION AND BROWN GAS

( Hung Kuk Oh ) 한국감성과학회 2001 춘계학술대회 Vol.2001 No.-

Physical chemistry states that electric potential is due to Gibb``s free energy from chemical reaction of the electric cell. However we have not the electromagnetic meaning of Gibb``s free energy. the free energy is discovered to be a kinetic energy part of the rotating electromagnetic wave (π-ray), which is different from conventional Coulomb attraction energy and can anticipate that there is a current difference between before and after the electric load. This paper manipulates the relationship between π-rays (Gibb``s free energy) and electrolysis, cell reaction and brown gas reaction.

DYNAMICS OF OPEN II-RAYS (META PHYSICS) AND CLOSED II-RAYS

( Hung Kuk Oh ) 한국감성과학회 2000 춘계학술대회 Vol.2000 No.-

The imploded open rt-rays comprise of the space and their diameters are distributed from nearly zero to infinite. The change of the potential energy in the open rt-ray produces an attraction force between them and it is sensible to the geometric shape factor and its frequency. The equivalent principle of general relativity means that in the wave equation its velocity of the force wave is infinite. The change of the state in a open rt-ray( or any force wave) can be transferred to any sensible open rt-ray via space at a finite velocity. Many properties of the light wave can be deduce from the motions of open rt-rays. The nonsteady and steady Schrodinger equations include the dynamics of open rt-rays and closed rt-rays. II-ray is a tool of entity for constructing physics and metaphysics at the same time.
