摘要： An apparatus for rolling of a powder metallurgical metallic workpiece is provided having a feeding device, a first induction heating apparatus in operable communication with a first RF generator and at least a first hot rolling mill. A process control device monitors at least one parameter of the first RF generator and outputs a signal. A method for continuous rolling of a metallic workpiece is also provided using the apparatus for rolling. The process control device signal can be used to monitor metallurgical properties of the workpiece and provide in-line evaluation of the workpiece.

摘要： A method of manufacturing an improved FenullNi alloy consisting of 33-37% Ni; 0.001-0.1% Mn; optionally, 0.01-2% Co; and at least one of (1) 0.01-0.8% Nb; (2) 0.01-0.8% Ta; and/or (3) 0.01-0.8% Hf, with the total of Nb, Ta and Hf being in the range of 0.01-0.8% and the remainder being Fe and unavoidable impurities. The method comprises subjecting the alloy to a hot rolling process wherein the rate of distortion during each pass of hot rolling is below 70/second resulting in the alloy having a reduced rate of crack formation during the hot rolling process, and high drop-shock resistance and low thermal expansion after the hot rolling process.
摘要翻译：一种由33-37％Ni构成的改进的Fe-Ni合金的制造方法; 0.001-0.1％Mn; 任选地，0.01-2％Co; 和（1）0.01-0.8％Nb中的至少一种; （2）0.01-0.8％Ta; 和/或（3）0.01-0.8％Hf，其中Nb，Ta和Hf的总量在0.01-0.8％的范围内，余量为Fe和不可避免的杂质。该方法包括对合金进行热轧过程，其中每次热轧过程中的变形率低于70 /秒，导致合金在热轧过程中裂纹形成速率降低，并且具有高的耐跌落冲击性热轧后的热膨胀率低。
