| titleOfInvention | Titanium clad steel sheet good in workability and production thereof |
| abstract | PURPOSE: To obtain a titanium clad steel sheet good in workability by limiting both the content of hydrogen and nitrogen contained in titanium and the range of the componental composition in steel of the base material and limiting the temp. range in a time for hot rolling and heating. n CONSTITUTION: Amount of oxygen and hydrogen contained in titanium is regulated to 0.15% and 0.01% respectively as the upper limit and deterioration of flexural properties is prevented. Amount of nitrogen contained in titanium is regulated to ≤0.04%. When steel of the base material is regulated to ≤0.1% C, ≤0.1% Si and ≤0.5% Mn, drawing is enabled as working of a thin steel sheet. Furthermore, when one or more kinds of ≤0.1% Al, ≤0.5% Ti, and ≤0.5% Nb are incorporated in this conditions, deep drawing is enabled. Heating temp. in a time for hot rolling and heating is regulated to 700-950°C. When copper is especially utilized as the intermediate medium bonding material and a molten intermetallic compd. of titanium and copper is utilized and junction is performed in the atmosphere, the lower limit temp. is regulated to 850°C. Furthermore the amount of hydrogen and oxygen contained in nitrogen being the annealing atmosphere is regulated to ≤0.2% and ≤0.5% respectively and dew point is regulated to -25°C or below. It is prevented that hydrogen and oxygent infiltrate into the titanium layer and that workability is deteriorated. Annealing temp. is regulated to 600-750°C and annealing time is regulated to 0.2-10min. Growth of the intermetallic compd. in the interface is inhibited and workability of titanium and steel of the base material can be exhibited. n COPYRIGHT: (C)1991,JPO&Japio |
