The experimental and theoretical analysis of thermodynamical peculiarities heat flux at the fatigue crack tip during its propagation was made in presented work. goal is to elucidate relation between flow kinetic for different loading conditions. plane specimens with notch from stainless steel (AISI 304) were studied. There two types uniaxial one type biaxial loading. A dissipation measured by s...

Abstract The abundant use of cutting fluids in surface grinding process and the corresponding costs energy consumption have been a major sustainability concern. This paper identified optimum depth cut for under controlled parameters using compressed air cooling technique dry cutting. morphology subsurface defects workpiece material (AISI 304 stainless steel) were measured compared. It was obser...

AE monitoring from various types of stress corrosion cracking (SCC) has been conducted for the past 15 years in our laboratory. This paper discusses AE results of active-path dissolution-type SCC of austenitic stainless steel in chloride solution and fused salt, fluoride and polythionic acid solutions, brass in ammonia (Mattosson's solution), and carbon steels in nitrite solution. Transgranular...

The purpose of the tests was to determine whether and how sterilisation process of samples made of AISI 316L stainless steel with diff erent strain impacts their corrosion resistance. Tests were made on steel samples that had been electrochemically polished in order to assure proper surface roughness. In order to evaluate the infl uence of sterilisation on physical and chemical properties of st...

Powder metallurgy (P/M) technique is usually used for manufacturing porous metal materials. However, some P/M materials are limitedly used in engineering for their performance deficiency. A novel 304 stainless steel P/M material was produced by a solid-state sintering of 304 stainless steel powders and 304 short stainless steel fibers, which were alternately laid in layers according to mass rat...

The mechanical properties of medium carbon steel (0.36C) were investigated under two different quenching media (water and palm oil). The properties are: the strengths, impact and hardness of the material. The investigations centered on unheat treated, normalized; water and palm oil quenched, and tempered conditions. The tempering temperature is 200°C. An AISI steel of grade C1035 was used for c...
