摘要： A method of forming a canister by means of a mechanical bonding of respective layers of a first metal material (tantalum) and a second metal material (niobium) to form a sheet stock, thereby forming the sheet stock into a canister form, wherein the first metal material comprises tantalum and the second metal material comprises at least one of niobium, molybdenum, or steel. The completed canister comprises a first metal material comprising tantalum, and a second metal material mechanically bonded to the first metal material by subjecting the first and second metal materials to at least 1,000,000 psi, to thereby form a canister having an inner diameter of 13-19 millimeters (mm), the second metal material comprising at least one of niobium, molybdenum, or steel.

摘要： A finish heat treatment apparatus for an iron powder. Raw iron powder is placed on a continuous moving hearth and continuously charged into the apparatus. In a pretreatment zone, the raw iron powder is subjected to a pretreatment of heating the raw iron powder in an atmosphere of hydrogen gas and/or inert gas at 450 to 1100° C. In decarburization, deoxidation, and denitrification zones, the pretreated iron powder is subsequently subjected to at least two treatments of decarburization, deoxidation, and denitrification. In the pretreatment zone, a hydrogen gas and/or an inert gas serving as a pretreatment ambient gas is introduced separately from an ambient gas used in the at least two treatments is introduced from the upstream side of the pretreatment zone and released from the downstream side so as to flow in the same direction as a moving direction of the moving hearth.

摘要： A blade member for cutting-tools includes a cermet substrate which contains, apart from unavoidable impurities, a binder phase and a hard dispersed phase. The binder phase contains 5% to 30% by weight of cobalt and/or nickel. The hard dispersed phase contains a balance composite carbonitride of titanium and one or more of the elements tungsten, molybdenum, tantalum, niobium, hafnium and zirconium. The composite carbo-nitride satisfies the relationship 0.2.ltoreq.b/(a+b).ltoreq.0.7, where a and b denote atomic ratios of carbon and nitrogen, respectively. The substrate includes a hard surface layer in which the maximum hardness is present at a depth between 5 .mu.m and 50 .mu.m from a substrate surface thereof. The substrate surface has a hardness of 20% to 90% of the maximum hardness.

摘要： A process for the deoxidation of a refractory metal containing minor concentrations of oxygen is disclosed. In this process the refractory metal is contacted with a metallic deoxidant in a dry, inert atmosphere. The metallic deoxidant and the refractory metal are heated to at least liquefy the metallic deoxidant and at least partially deoxidize the refractory metal. The refractory metal is thereafter cooled and contaminants on its surface are removed.

摘要： The invention relates to a process for the production of mild steel tubes suitable for heating installations. Coils of the tubes of mild steel are enclosed in a container and introduced into a furnace and there heated without the addition of protective gas up to a temperature between 640* and 900*C. When this temperature is reached wet hydrogen is introduced into the container in the furnace in order to lower the carbon and nitrogen contents of the steel and increase the size of the grains. Finally the container with the tubes is transferred to a cooling pit in order to cool.
