induction melted heat of high-temperature alloy being poured in P & W A's experimental foundry. Molten metal is strained into large water tank# forming metal shot which is remelted and cast into test specimens and experimental parts. Deve/apment and evaluation of improved high-temperature alloys for advanced jet engines is one of the challenges facing meta/lurgists at P 40 GINEERING AND SCIENCE
The development of more a& ancedy far more powerfuJ aircraft engines depends to a high degree on the development of new and improved materials and nietllods of processing them. Such materials and methods, of course, are particularly important in the nuclear field. At Pratt & Whitney Aircraft, the physical, metal1urgica1, chemical and mechanical properties of each new material are studied in minute detail, compared with properties of known materials, then carefully ana- lyzed and evaluated according to their potential usefulness in aircraft engine application. t~ffects of radiation on matter are irnpurtzint aspects of the nuclear reactor program now under P & W A. Stress analysis by strain gage and X-ray diffraction is another notable phase of investigation. In the metallurgical field, materials work involves studies of corro- sion resistance, high-temperature mechanical and physical properties of metals and alloys, and fabrication techniques. Mechanical-testing work delves into design and supervision of test equipment to evaluate fatigue, wear, and elevated-temperature strength of materials. It also involves deter- In the field of chemistry, i~ivcsti- gations are made of fuels, high-teni- perature lubricants, elastolneric compounds, electro-chemical and 5r- ganic coatings. Inorganic substances, too, must be prepared and their properties determined.
