固溶退火

固溶退火亦即碳化物固溶退火, 一种将成品件加热至1850 deg F(摄氏1010度)以上而脱除碳化物沉淀(即从不来自锈钢固体溶液中逃逸的碳)的工艺,此后将其迅速降温,通首色含坐新类混需死常是用水淬火, 所含械职厂非延碳化物返回不锈钢固体溶液中。

• 中文名称 固溶退火
• 外文名称 solution annealing
• 解释 碳化物固溶退火
• 应用范围 不锈钢铸件的固溶处理能产
• 容器 在非常压批式炉进行热处理

　　应用范围

　　固溶退火处理可应用于一系列的合金钢与不锈钢成分中. 对于300系列不锈钢铸件的固溶处理能产生一种没有来自碳化物杂质的均一简优吗密线课分细变所爱的显微结构. 对于沉淀硬化合360百科金铸件及锻件的固溶退火能产生较软的显微结构,更适于精密公差的机加工.这些合金在以最小畸变的精密公差机加工之后,有着时效硬化的潜在倾向.这些材料及工艺对有中目等强度要求的车削或螺旋机件上有着普遍的应用. 这种热处理可以依照部件所需的尺寸,几何形状与表面条师齐夜固农须编执五空件,成批的在大气炉,非常压炉或真空炉中进行.小型部件也可以在连续氢气带式炉中热加工.

　　固溶退火与时效硬化也可用于铝合金的冲压件和铸件. 通常是在非常压批式炉进行热处理,在固溶退火之后用水对部件淬火.时效硬化则在大气中用电炉或燃气炉成批操作.

　　SOLUTION ANNEALED (same 酸督当放翻as CARBIDE SOLUTION ANNEALED) : A process of heating and removing carbide precipitants (carbon 刻飞鲜兰活急很that has broken l概福谈你拿受应团在oose from i倍亮手那逐内待映杀置育ts stainless steel solution) by heating a finished fitting to over 1,850 degrees F. and cooling it quickly, usually in water, so carbon co行ntent goes back into the stainless solution.

　　Solution 迫两盾annealing treatmen静们坐山三沙宜苏清值ts are applied to a series of alloy steel and stainless stee亮兰什临包使无爱营l compositions. Solution annealing of 300 series stainless steel cas局革议后tings produces a uniform microstructure free of carbides in the microstructure. Solution annealing of precipitation harden亚松不说宪记却岩育改州ing cast and wrought alloys produce味提绿致教延翻s a soft microstructure suitable for m新菜念achining to close toler文ances. These alloys have the pot培ential for Age Hardening af席未清陆圆矛存诗ter machining with minimal distortion of close dimensional tolerances. These materials and processes are generally applied to medium strength requirements on turned or screw machine parts. The heat treatments may be performed in batch atmosphere furnaces, non-atmosphere furnaces, and vacuum furnaces, depending on the part size, geometry, and surface condition required. Small parts may also be treated in continuous hydrogen belt furnaces.

　　Solution annealing and age hardening may also be applied to aluminum alloy stampings and castings. These treatments are usually performed in non-atmosphere batch furnaces with water quenching of the parts after solution annealing, and age hardening in electric or gas fired batch furnaces in air.
