Filed: 1995-05-31
Abstract: PURPOSE: To make it possible to obtain an Mg-group composite material having decreased defects at a low manufacturing cost by adding a specific amt. of Ca to specific molten metal and stirring the molten metal. CONSTITUTION: A high-frequency induction furnace 6 is enclosed by a chamber 7 and an atmosphere gas, such as gaseous Ar, is fed therein. An Mg ingot is heated in the atmosphere in the induction furnace 6 to form the molten metal 3a. SiO2 is, thereupon, mixed as a penetration assistant into SiC powder. The Ca is added at 0.01 to 0.1wt.% to the molten metal 3a formed by penetrating the melt of the Mg alloy which is the matrix to this powder mixture and the molten metal is stirred to prevent the formation of the flocculated lumps of the SiC. The stirring of the molten metal is lightly executed to prevent the atmosphere gas and the oxidized film on the molten metal surface from being taken into the molten metal. The dispersibility of the SiC in the molten metal is thus improved.

Title: Production of high tension wire
Inventor: KAJIKAWA KATSUYOSHI
IPC: C21D8/00
Filed: 1980-11-08
Abstract: PURPOSE: To obtain steel bars and steel wires of superior relaxation characteristics and absorption energy at the impact tensile breakdown by cooling the steel wire which is fined of austenite grains by controlled rolling to a hardened structure, and warm working martensite under specific conditions.  
     CONSTITUTION: After steel of ≤0.5% content of C is rolled at above the Ar 1   point, it is cooled at above the critical cooling rate to a hardened structure.  Such wire rod is heated to 100W700°C, and is subjected to plastic working or  straightening of 3W90% strain rates at these temp. regions, whereby a high tension wire is obtained. Here, if the rolling is below the Ar 1  point, proeutectoid  ferrite deposits, resulting in considerably degraded hardenability and ductility.  Relaxation is markedly decreased by the above-described plastic or straightening working, and at the same time, the increase in mobile dislocation degrading  this is suppressed. The working temp. thereof is required to be above the lower  limit, but in excess of the above limit, the effect and strength decrease. If the  content of C exceeds 0.5%, the warm working of martensite is difficult. With  the strain rates below the lower limit, the decrease in relaxation is not realized,  and above the upper limit, the working is difficult.
