Title: Al alloy brazing sheet for executing low vacuum brazing excellent in brazing quality
Inventor: ITAGAKI TAKESHI
IPC: B23K35/28
Filed: 1993-04-02
Abstract: PURPOSE:To execute excellent brazing of an Al alloy brazing sheet in the low vacuum condition. CONSTITUTION:The brazing filler metal containing 0.2-0.8% Mg and 5-15% Si as the basic components is cladded on one side or both sides of an Al alloy core where 0.2-1.2% Mg is contained as the basic component, and the content of Si and Cu in the inevitable impurities are regulated to <=0.1% and 0.05% respectively. When requested, Mn, Zr, Cr, Ti, V and Fe of the prescribed amount are added as the components of the core, and Bi and Be of the prescribed amount are added as the components of the brazing filler metal. In addition, the peripheral length of the crystalline grain of the core after brazing and heating is regulated to 400-600mum. This constitution allows the excellent brazing under the low vacuum condition, and the reduction in the strength by the pollution in the surface due to the presence of Mg and Mg transpiration can be previously prevented. Moreover, the brazing quality can be further improved by regulating the peripheral length of the crystalline grain of the core.

Title: Rust preventing and vibration damping steel sheet and its manufacture
Inventor: TOKUNAGA YOSHIKUNI
IPC: C23C2/28
Filed: 1983-06-02
Abstract: PURPOSE:To obtain a rust preventing and vibration damping steel sheet having Zn alloy layers with superplasticity at room temp. formed by hot dipping by restricting the grain size of a Zn alloy contg. a specified amount of Al plated to a steel sheet by hot dipping. CONSTITUTION:A steel sheet is coated with a Zn alloy consisting of 0.15-1.5% Al and the balance Zn by hot dipping. When the coated steel sheet is cooled, it is rapidly cooled from >=420 deg.C to 380 deg.C at >=10 deg.C/sec cooling rate to adjust the grain size of the Zn alloy plated to the steel sheet to <=5mum. The resulting steel sheet has high adhesion because the Zn alloy layers show superior deformability when the sheet is press-formed, and the steel sheet has superior vibration damping capacity at room temp. - about 250 deg.C high temp., so it is especially useful as the material of parts around an engine.
