Title: Baked flux for submerged arc welding
Inventor: SUGIOKA ISAO
IPC: B23K35/362
Filed: 1985-04-19
Abstract: PURPOSE:To decrease hygroscopicity by incorporating fine granular alumina having a specific particle size at prescribed % into a raw material prior to baking. CONSTITUTION:The fine granular alumina sized <=10mum is incorporated at >=3wt% into the flux raw material consisting of siliceous stone, limestone, fluorite, etc. in which >=10mum particle sizes occupy the greater part. Water glass is added to such raw material and the mixture is granulated.

IPC: C22C21/00
Filed: 1983-05-13
Abstract: PURPOSE:To obtain an alloy having high wear resistance and strength by dispersing fine particles for strengthening to be dispersed in Al matrix into fine dendrite as well and specifying the size of the dendrite as well as the grain size, intergranular distance and volume ratio of said fine particles. CONSTITUTION:The size of dendrite is more preferable as the size is smaller and is made <=20mu. Fine particles for strengthening are the oxide, carbide, nitride, etc. of Si, etc. which exist stably in Al matrix at a high temp. without growing to or forming coarse grains, and the grain size thereof is made <=0.5mu in order to obtain substantial dispersion strengthening. The intergranular distance of the fine grains is more preferable as the size is smaller and is made <=30mu. The larger the amt. of the fine particles, the better but if the amt. exceeds 20% by weight, substantial dispersion strenghtening cannot be obtained and mixed dispersion is difficult and therefore 20% is the upper limit. The fine particles for strengthening are uniformly dispersed in a molten eutectic Al alloy and thereafter pressurized and cooled quickly to satisfy the above-mentioned conditions, by which the intended alloy is obtd.
