This paper describes damping capac i t y and mechanical p roper t ies o f Zn-8-20%A1 and Zn-8-20%Al-0.02-0.04XMg a l l o y cast ings. Zn-8-20%A1 a l l o y casti ngs show h igh damping when quenched from 573K. Small amount o f Mg a d d i t i o n t o these a l l o y cast ings lowers damping capaci ty considerably b u t e f f e c t i v e t o reduce decomposition through aging a t 423K f o r 48hrs ...

Suppose that for an arbitrary function $f(x,y)$ of two discrete variables, we have the formal expansions. [f(x,y)=sumlimits_{m,n=0}^{infty }a_{m,n},P_{m}(x)P_{n}(y),] $$‎ ‎x^{m}P_{j}(x)=sumlimits_{n=0}^{2m}a_{m,,n}(j)P_{j+m-n}(x)‎,$$ ‎we find the coefficients $b_{i,j}^{(p,q,ell‎ ,‎,r)}$ in the expansion‎ $$‎ ‎x^{ell }y^{r},nabla _{x}^{p}nabla _{y}^{q},f(x,y)=x^{ell‎ ‎}y^{r}f^{(p,q)}(x,y) =sumli...
