Abstract：The dispersion-strengthening phenomenon in an austenitic heat-resisting steel(ЭИ257)has been studied.The specimens are composed of powder ЭИ 257,blended with Al_2O_3,MgO,ThO_2,ZrO_2,or Nb_2O_5.The changes in hardness,at room or high temperatures,of the speci-mens with various compositions,show that the dispersion-strengthening effect in the steelis quite remarkable.The experiments gave the following results:(1)When a heat-resisting steel(ЭИ 257)is dispersion-strengthened with oxidepowder,its heat-resisting temperature for comparable hot hardness may be increasedfrom 650℃ to 900℃.(2)Al_2O_3 is the best among the five oxides,and 8—10 volume percent Al_2O_3 isthe best of all.(3)Dispersed oxide raises the recrystallization temperature. 收稿日期: 1963-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 刘民治 白福山 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1963/V6/I1/59 [1] Irmann,R.:Rev.Aluminium,1951,28,(179) ,269． [2] Bruckart,W.L.,Jaffee,R.I.:Symposium on Metallic Materials for Service at Temperatures above 1600°F.(ASM,1955) ,p.111． Robert,I.J.:The Metal Molybdenum,(ASM,1958) ,p.354-364． [3] Gatti,A.:Trans.AIME,1960,218,437． [4] Gregory,E.,Goetzel,G.:Trans.AIME,1958,212,868． [5] Blainey,A.:Metal Progr.,1958,74,(3) ,95． [6] Adkins,E.F.,Sims,C.T.,Jaffee,R.I.:Trans.AIME,1959,215,344． [7] Gatti,A.:Trans.AIME,1959,215,753． [8] Yunoshin,I.,Hiroshi,H.:Sci.Rept.Res.Inst.Tohoku Univ.,1960,A12,168． [9] Orowan,E.:Symposium on Internal Stresses in Metals and Alloys,(L M.,London,1947) ,p.451． [10] Coulomb,P.,Friedel,J.:Dislocations and Mechanical Properties of Crystals,(Wiley,1957) ,p.555． [11] Ansell,G.S.:Trans.AIME,1959,215,294． [12] Towner,R.J.:Metal Progr.,1958,73,(5) ,70． [13] Sugarman,B.:Symposium on Powder Metallurgy,(ISI,1954) ,p.175． [14] #12 [15] 刘民治等:“表面活性介质在机械加工过程中的作用”,未发表.
