Electromagnetic railgun attracts more and attention due to its advantage in speed, cost, obscurity. It is found that the rail should withstand huge mechanical thermal shocks during launching operation. The forms of failure are accompanied by gouge, grooving, transition, arc ablation, etc. service life has become a bottleneck restricting development electromagnetic technology. A series researches carried out solve failure, including analysing mechanism using various advanced materials. This...
Undeformed face-centred cubic (FCC) high-entropy alloys (HEAs) always possess excellent plasticity but low hardness. In this work, Al alloying on the surface of a CrCoFeNi FCC HEA is realized by laser technique. An Al1.5CoCrFeNi body-centred (BCC) in-situ generated HEA. The well-bonding BCC layer possesses hardness as high 536 HV. hard results in much lower wear rate Al-alloyed specimen than pristine specimen. This study provides simple strategy to harden HEAs formation through alloying.
We investigate here the thickness effect on microstructures and mechanical properties of a quenched tempered 178 mm ASTM A517 GrQ steel. The at sub-surface, 1/4 (t/4), 1/2 (t/2) were characterized. A comparison hardness, strength, impact toughness different positions shows that lowest strength occurred t/2, where mixture coarse, martensite bainite found, their inter-lath boundaries occupied with highly dense, film-like or spheroidized carbides. cooling rate for transformation was measured to...
In this paper, two low carbon microalloyed steels, named as steel A and B, were fabricated by ultra fast cooling (UFC). both the microstructures containing quasi polygonal ferrite (QF), acicular (AF) granular bainite (GB) can be obtained UFC process. The amount of AF in B is more than that A. size distribution precipitates (Nb/Ti carbonitrides) are finer dispersed those due to relatively finish temperature. mechanical properties steels effectively enhanced process produces low-temperature...
