The effect of cold swaging and subsequent annealing on the structure mechanical properties a 321-type metastable austenitic stainless steel was studied. Cold to strain 90% produced gradient with gradual decrease in α-phase content from edge center bar. Globular lamellar regions both strain-induced martensite retained austenite were found center, meanwhile, completely globular austenite–martensi...

This paper investigates the microstructural evolution and grain refinement kinetics of a solution-treated Cu-0.1Cr-0.06Zr alloy during equal channel angular pressing (ECAP) at a temperature of 673 K via route BC. The microstructural change during plastic deformation was accompanied by the formation of the microband and an increase in the misorientations of strain-induced subboundaries. We argue...

Quartz crystal microbalance with dissipation monitoring (QCM-D) has been employed to study the assembly and recrystallization kinetics of isolated SbpA bacterial surface proteins onto silicon dioxide substrates of different surface wettability. Surface modification by UV/ozone oxidation or by vapor deposition of 1H,1H,2H,2H-perfluorododecyltrichlorosilane yielded hydrophilic or hydrophobic samp...

Abstract The work presents results on the effect of prior martensite formation bainite transformation kinetics in a 3% medium-Mn multiphase steel. material was subjected to two isothermal holding temperatures: 400 °C (without martensite) and 350 (with martensite). According obtained dilatometric results, leads acceleration kinetics. starts finishes much faster, when present before holding. micr...

Adiabatic shear banding during high speed machining is important to understand material removal mechanisms. This paper investigates the microstructure of adiabatic shear bands (ASBs) in the serrated chips produced during the high speed machining of AISI 1045 hardened steel. Optical microscope, scanning electronic microscope(SEM) and transmission electronic microscope(TEM) were used to explore t...
