laser heat treatment meaning in English
激光热处理
Examples
- The question of beam parameters expression in laser heat treatment is also discussed
最后，对激光热处理中光束参数表述问题进行了研究。 - Discussion on the transient of non - fourier heat conduction law and laser heat treatment
强瞬态非傅立叶导热效应判据与激光冲击硬化应用的探讨 - We studied the effect of laser quenching ( harden by phase transformation ) on some representative mould steels . through measuring the rigidity on the surface of samples treated by laser heat treatment , and through photographing microstructures of the steel surface , we find many reasons attribute to high hardness . these reasons include ultra - fine grains , high density dislocation and more content of carbon in martensite
我们研究的是激光淬火对几种典型模具钢的作用，通过对热处理后的试样的硬度分布的测定，用金相和电镜观察金相组织的变化，认为激光热处理产生高硬度的原因是晶粒细化、高的位错密度和高的马氏体含量。 - This is due to the fact that laser beams with a flat - top profile or other kinds of profiles are desired in various applications , such as in the applications of laser fusion , laser heat treatment and optical data processing etc . nevertheless most of study on the beam shaping is concentrated on the beam shaping of spatially completely coherent beams
光束整形之所以热门,是因为这些特殊形式的光束可应用于激光光学及生物医学等领域。例如,平顶光束可应用于激光核聚变、激光热处理等领域。然而,研究者对部分相干光的光束整形的研究还很少。 - In chapter four , in our experiments , we selected four representative mould steels as samples . after laser heat treatment , the hardness of samples was measured by special instrument , microstructure was also photographed to be analyzed carefully . through these experiments , we also debated on the theories which explain the new phenomenon occurring in laser overlapping treatment
