Int.rnal frict.on peaks associat.d wit. t.e presence of hydrogen in eight.t.pes of high chromiumnickel alloy st.el were observed in measurement. wit. a t.rsion pendulum. t.e opt.mum t.mperat.re for maximum int.rnal frict.on lies bet.een 610—640℃ for a frequency of vibrat.on of about.1.5 cycles per second. Syst.mat.c invest.gat.ons were made wit. specimens cont.ining 18% of Cr and 12% of Ni. t.e element.ry process for t.is int.rnal frict.on peak was found t. be a relaxat.on process, associat.d wit. an act.vat.on energy of about.46,000—50,000 calories per mole. Judging from t.e value of t.is act.vat.on energy, as welt.as from t.e behavior of t.t.int.rnal frict.on peak when t.e measurement. were t.ken while t.e t.mperat.re was raised, lowered, and kept.const.nt. t.e conclusion was reached t.at.t.e new int.rnal frict.on peak is associat.d wit. t.e st.ess-induced micro-diffusion of hydrogen molecules in high alloy *** frict.on measurement. were also able t. disclose t.e t.mperat.re range in which t.ansformat.ons bet.een hydrogen molecules and hydrogen at.ms were t.king place in 18Cr12Ni alloy st.el specimens for a given rat. of heat.ng and cooling. t.e result. obt.ined are in agreement.wit. t.ose found in lit.rat.re.

研究了304不锈钢双辊薄带连铸中控制凝固组织的因素,观察到了从铁素体到亚稳态奥氏体最初凝固状态的转变,此转变是由于溶体在冷铸辊附近达到10~3KS^(-1)级相对高的冷速而过冷造成的。原始奥氏体凝固程度取决于不同的熔体装入置之间可能... 详细信息

研究了304不锈钢双辊薄带连铸中控制凝固组织的因素,观察到了从铁素体到亚稳态奥氏体最初凝固状态的转变,此转变是由于溶体在冷铸辊附近达到10~3KS^(-1)级相对高的冷速而过冷造成的。原始奥氏体凝固程度取决于不同的熔体装入置之间可能的合金成分的波动,且从临近带钢表面的一些局部奥氏体区到凝固带的完全奥氏体间会产生变化。作为原始铁素体的凝固区,发现了不均匀的Ni,Cr定向偏析,而作为原始奥氏体的凝固区发现了此两元素均匀的定向偏析。磁测量表明:铁素体体积百分数在原始铁素体凝固薄带中变化约为1.3到1.9体积百分数,而凝固为原始奥氏体的试样中,变化量约在0.1到0.2的体积百分数。
