    In order to determine the workability of cast iron with spheroidal graphite,the following tests have been conducted on this material in the as-cast and annealed condition:tensile tests,compression tests,Charpy impact tests,impacttensile tests,twisting tests,upsetting tests under the drop hammer and small-scaledrolling tests.Results from these tests show that the best hot-working temperature rangeof this material varies somewhat with the stress system applied and the speed ofworking,and in general lies between 700° and 1100℃.Within this temperaturerange,the maximum amount of working permissible for a single working operationvaries considerably with the stress system applied.Under tensile stresses,thismaximum amount of working lies between 28 and 57.6%;under predominentlycompressive stresses,it lies between 58.5 and 72.9%;while in the small-scaledrolling tests,the maximum reduction in thickness permissible for a single passlies between 38.6 and 44.3%.The maximum amount of working permissible is alsoaffected by the speed of working,being greater at lower speeds.Tests on industrial scale show that the upsetting and small-scaled rollingtests give results nearest to those from industrial tests.Charpy impact tests,impacttensile tests,upsetting tests and small-scaled rolling tests show more prominentlythe best hot-working temperature range than the other tests conducted.Results of the present research also indicate that cast iron with spheroidal graphitehas a higher strength and workability when subjected to compressive stresses thanto tensile stresses,that a brittle temperature range has been recorded between200° and 650℃,which varies with the speed of test.Judging from the variationof the resistance to deformation with the change of temperature and the speedeffect,this phenomenon is associated with blue brittleness.

    This paper described deformation and recrystallization in (110)[00l] single crystals of iron-silicon (3.25%) which reduction of thickness 5-50%. In the range of a reduction 2-16%, the slip planes ate (101), (101), (110) and (Tl0); and the twinning planes are (112) and (112). Which coincided satisfactorily with our explanation on the formation of cold-rolling textures in (110) [001] singe erystals of iron-silicon alloy.

    本文研究了含硅3.25%铁硅合金(110)[001]的单晶,在压下量为5—50%范围内的形变和再结晶。沿样品轴向冷轧2—16%后,测出的滑移面为(101),(101),(011)和(011),孿生面为(112)和(112),这很好地解释了本文所得冷轧机构的来源。 样品经过35%和50%冷轧后,在退火时再结晶晶粒形成的部位和生长的情况有所不同:前者在孿晶界上领先形成,并沿孿晶界择尤生长;而后者除了观察到在孿晶界和形变带附近形成外,还观察到一种通过亚晶粒长大而成的晶粒,它们择尤生长的趋势也不如前者明显。

    样品是工业纯铝,直径1.665毫米,长24厘米的铝丝,测量它拉伸过程中电阻率的变化。得到的结果:形变率ε<8.5%时,电阻率减少。当ε>8.5%,电阻率开始上升。至ε=12.5%△ρ=0。以后△ρ为正值。为了探讨电阻率改变的本质,还测量了退火对电阻率的影响和铝丝在高温淬火后电阻的变化。根据这些实验结果,试图进一步探讨范性形变对铝电阻影响的本质。
