实验过程
The chemical compositions of the steels used in the present study are listed in TABLE.2.
在当前研究用到的钢铁的化学物质组成在表2中以列出.
The steels were melted as vacuum-induction melts in 150 kg ingots with a base composition of 0.09%C-1.6%Mn-0.02%Al-0.002%N. After hot forging the steels were hot rolled to 20mm thick plates.
钢铁在真空内燃机中(或是真空诱导环境下?)被融化.钢铁以150千克锭为单位大小,基本组成为 0.09%炭-0.02%铝-0.002氮(?).在高温锻造后,刚被碾压成20毫米厚度的钢板.
Steels A1 to A3 were used for the experiment on the solubility of complex precipitates.
A1到A3号钢在复杂沉淀物可溶性实验上.
Small test pieces (20mm x 30mm x 120mm) machined from the steels were solution treated at a temperature between 900 and 1250'C for 5h followed by water quenching.
以钢为原料按规格制造的实验体(22毫米*30毫米*120毫米)在900-1250度的温度下经过5小时做溶解处理,之后用水冷却.
Precipitates were extracted with carbon replicas from the specimens for observation.
用炭REPLICA(复制品)将沉淀物从样本中取出做观察.
Compositions of the individual particles on the replicas were measured by the STEM-EDX quantitative microanalysis.
将在REPLICA上的微粒组合物用STEM-EDX微量分析(器/方法?)测量.
Total amount of mlcroalloys in precipitates in solution treated specimens were determined by the chemical analysis of electro-chemically extracted residue.
所有的样本中沉淀物溶液中的MICROALLOY微合金用电气化学提取残渣的化学分析法来确定其成分.
For the experiment on the kinetics of strain-induced precipitation after hot deformation, steel-B was used.
样本钢B被用来做,经高温变形的沉淀物的动力张力实验.
Cylindrical specimens of 8mm in diameter and 12mm in height were machined from the steels.
以8毫米为直径12毫米为高度的圆柱样本从钢中按规格制造.
After solution treatment at 1250'C for lOmin, the specimens were cooled to a precipitation temperature between 1OOO and 900'C, and then compressed at a strain rate of 1s.
在1250度经过10分钟的溶解处理,样本被冷却到900-1000度的沉淀温度,然后在1S的力度下被压缩.
After the deformation, they were held at the precipitation temperature for various period (O to 3OOOsec) followed by water quenching.
在变形处理之后,他们以1-3000秒的存在时间,存在于沉淀温度下,之后用水冷却.
In order to investigate the effect of hot deformation on precipitation kinetics, the precipitation tests without deformation were carried out.
为了调查高温变形在沉淀物动力(动能?)方面的作用,进行不经变形的沉淀实验.
Volume fraction of precipitates were determined by means of chemical analysis of microalloys in the electro-chemically extracted residue from the specimens.
沉淀的碎片量由电气化学法从样本中提取残渣的的化学分析为合金法来确定.
