"Non-ferrous copper base alloys find many applications in industry. Among these alloys one finds the tin bronzes rather widely used for many purposes, and by delving still farther one finds pressure castings as one of their important applications. In many foundries the percentage of rejections due to leakage or porosity is quite high. This is obviously very costly since leakage is generally only found after machining. It is with a view to determine the causes for leakage in pressure castings and to devise methods for its prevention that the work described in this thesis was undertaken. It is not intended to cover the subject completely. Furthermore, the author wishes to direct attention to the fact that the work was conducted primarily to increase the knowledge on the behavior of these alloys under certain controlled conditions and that no attempt was made to adhere to existing specifications other than chemical composition"--Statement of Problem, page 1.
