Pb-SiおよびPb-Sb-Si合金の耐クリープ性について

抄録

In this paper, the change in creep resistance of lead and lead-antimony alloys due to silicon content is described. Specimens used in this study were extruded wires of 2 mm diameter and the testing temperature was from 29 to 31°C. The results obtained were as follows: (1) The creep resistance properties of lead and lead-antimony alloys were improved by addition of silicon. An increase of silicon and antimony content in lead seemed to increase the creep resistance at high stress. (2) The creep rate in 100 hrs of lead and its alloys was decreased generally by addition of silicon. (3) The time required for 1% elongation in lead-silicon alloys was longer than in lead, in lead-antimony-silicon alloys was generally longer than in lead-antimony alloy and the value at low stresses was similar to that of lead.
