Title: High strength cemented carbide
Inventor: SATO NAOTOSHI
IPC: C22C1/05
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To produce an alloy having high strength and usable for all fields even if coarse-particlulated WC powder is used by adding prescribed VC to raw material powder. SOLUTION: The WC powder to be used is coarse particles having 1 to 20μm average particle size. Since Co powder as bonding phases forms into liq. phases at the time of sintering, the particle size thereof is not particularly limited. Then, in this cemented carbide, VC powder as a particle growth inhibitor is added. The average particle size thereof is suitably regulated to <=10μm, and it is added to the raw material powder in the ratio of 0.5 to 3mass% based on Co. In this way, the defective strength of the cemented carbide is improved. It is because that the abnormal granular growth of WC in the cemented carbide is suppressed similarly to the case in which hyperfine WC particles are used.  When the abnormally grown WC is generated, in the case loads are applied to the cemented carbide, stress is concentrated on the abnormally grown WC to cause destruction and to reduce its strength. But, in the case the adding ratio of VC exceeds the upper limit value, (W, V) C crystallized out phases appear to deteriorate its strength (deflective strength), and it is no preferable.

Title: Fabrication of thin film
Inventor: HASEGAWA HITOSHI
IPC: C30B23/08
Filed: 1983-09-28
Abstract: PURPOSE:To prevent the expansion of an impurity-introduced region by a method wherein when a thin film is formed by reaction of a reactive gas with a substance to be deposited, the reactive gas is made into a cluster beam and is then ionized which is directed to the substrate with being accelerated so as to cause the reaction with the substance to be deposited thereby decreasing the substrate temperature to 800 deg.C or under. CONSTITUTION:The substance to be deposited e.g. of Al is fused and evaporated by use of an electron beam in a reactor in which the pressure is 10<-6>Torr, and N2 gas as a reactive gas is ejected from a nozzle onto an Si substrate to be made into a cluster beam. Next, the cluster is ionized by electron shower and is accelerated by acceleration voltage of 2kV to produce a thin film of Al on the substrate. Thus, the substrate temperature which is generally made to be 1,000 deg.C or over can be decreased to 800 deg.C or under thereby enabling the restrain of expansion of the impurity-introduced region. At the same time, as the internal stress distoriton consequent on heating and cooling is diminished, the good thin film can be obtained.
