摘要： A process for treating an article of metal containing material having a minimum cross-sectional dimension. The process includes providing the article at ambient temperature or below and completely immersing the article in a cryogenic fluid over a time period at least equal to 10 minutes times a value of the minimum cross-sectional dimension in inches. The process further includes withdrawing the article from contact with the cryogenic fluid, and immediately subjecting the article to a flow of gaseous fluid sufficient to raise the temperature of the article until the article reaches ambient temperature.

摘要： A thermal cycling apparatus having an upper heat chamber and a lower cold chamber positioned vertically beneath the upper heat chamber and vertically coaxial therewith whereby a material to the thermal cycle tested can be transferred between the upper heat chamber and the lower cold chamber. An externally operated flapper door within the thermal cycling apparatus separates the two chambers. The material to be thermally tested is placed in a basket constructed of suitable material which can be translated between the two chambers from a location externally of the chambers. The temperature in the upper chamber is elevated by gaseous nitrogen to a temperature up to about 1000 degrees F. and the lower cold chamber is cooled by a cryogenic liquid. Cycle testing is preformed by alternately transferring the material, i.e. 40 or more specimens at a time, between the upper and lower chambers the number of times desired.

摘要： High strength, high precision thin-walled cartridge cases are manufactured from a metal of interest selected from low alloy and carbon steels utilizing an extrusion and heat treating process. The cartridge blanks are extruded to a length greater than that necessary for the finished cartridge case and are provided with one or more peripheral grooves close to the open end of the extruded cartridge blank to prevent warpage during subsequent heat treatment.

摘要： A process for treating a material to improve its structural characteristics comprises the steps of suspending the material closely above a cryogenic liquid for between about two hours and about four hours and, thereafter, completely immersing the material from its suspended position into the cryogenic liquid within about two seconds to about ten seconds. The rate of evaporation of the cryogenic liquid is then controlled so that the material is completely exposed to only gases within about five hours to about ten hours and, subsequently, the temperature of the material is controlled to rise from the cryogenic level to about -50.degree. F. within about eleven hours to about sixteen hours. After the material temperature reaches about -50.degree. F. within the specified time, the material is then allowed to return to ambient temperature of between about 65.degree. F. and about 70.degree. F. Thereafter, the material is heated to a temperature within the range of about 330.degree. F. to about 370.degree. F. for between about one hour and about five hours. When the heating step is finished, the material is allowed to return to its ambient temperature and the process is complete.
