用应变退火法研究工业纯Fe、电解纯Fe,Fe-0.05wt-%Ti和Fe-0.5wt-%Ti合金的晶体生长.并讨论了临界应变和板厚对晶体生长的影响.由实验发现:Fe-0.28wt-%Ti合金冷轧薄板(约0.5—1mm厚)通过适当的一次湿氢(或干氢)高温退火就能长出较大的单晶.
The crystal growth of Armco iron,electrolytic iron and dilute solid solutionalloys,Fe-0.05wt-%Ti and Fe-0.5wt-%Ti,has been investigated by the strain-annealtechnique.The effect of the critical strain and sheet thickness on the grain growthproperties has also been discussed.It was found that the coarse single crystalscould be easily grown up in the cold-rolled Fe-0.28wt-% Ti alloy sheet about 0.1—1mm in thickness only by single high temperature annealing in a wet or dry H_2 atmos-phere without critical strain.
