Abstract  

The effects of experiment conditions on tensile strength and the inner uniformity of Li–B alloy ingot were investigated by using mechanical strength method. The results show that specimen orientation, test temperature and specimen thickness have remarkable influence to test results. The maximum diversity of strength is up to 36%, and texture of LiB compound fiber in the rolled alloy has significant effect to strength. The average strength of Li–B alloy is about 24.5 MPa at 21oC. For a ingot, strength in the center is higher than that on the edge, and that on the bottom is more than that on the top, but the density on the edge is beyond that in the center, and that on the bottom is more than that on the top too. The reason is the uneven distribution of coarse particle and fine particle of boron powder because of the influence of gravity and centrifugal force in the preparation process of Li–B alloy.
