Most widely held works by C. A Hoffman
Is it moral to modify man? by Claude A Frazier( Book )

2 editions published in 1973 in English and held by 561 WorldCat member libraries worldwide

This work explores ethic and moral issues in the medical field
An improved method and apparatus for analysis of impurities in helium by David E Emerson( Book )

3 editions published in 1970 in English and held by 46 WorldCat member libraries worldwide

Elevated-temperature combined stress-rupture plus fatigue strength of waspaloy having having different aging treatments and/or molybedenum contents by C. A Hoffman( )

2 editions published in 1958 in English and held by 19 WorldCat member libraries worldwide

Effects of some solution treatments followed by an aging treatment on the life of small cast gas-turbine blades of a cobalt-chromium-base alloy by C Yaker( )

2 editions published in 1951 in English and held by 12 WorldCat member libraries worldwide

The experimental results indicated that all treatments lengthened the time to initial failure and improved the mean life of the blades. These results were confirmed by a statistical analysis
Effects of thermal loading on composites with constituents of differing thermal expansion by Charles A Hoffman( Book )

3 editions published in 1970 in English and held by 11 WorldCat member libraries worldwide

Investigation of effect of notches on elevated-temperature fatigue strength of N-155 alloy by C. A Hoffman( )

4 editions published in 1954 in English and held by 9 WorldCat member libraries worldwide

An investigation of the effect of notches on the fatigue strength of N-155 alloy at elevated temperatures was conducted by the NACA in cooperation with the Gas Turbine Panel of the Joint A.S.T.M.-A.S.M.E. Committee on Effects of Temperature on the Properties of Metals. Studies were made at 1350 deg and 1500 deg F in completely reversed bending. The results on relatively few specimens indicated that: (a) Notches reduced fatigue strength at l350 deg F by approximately 34 to 40 percent and at l500 deg F by approximately 30 to 37 percent over the range of 3 to 150 hours, and (b) the notch sensitivity in fatigue under conditions of completely reversed bending at 1350 deg and l500 deg F was considerably less than that predicted for static bending under elastic conditions
Effects of some solution treatments followed by an aging treatment on the life of small cast gas-turbine blades of a cobalt-chromium-base alloy. 2 - Effect of selected combinations of soaking time, temperature, and cooling rate by C. A Hoffman( Book )

1 edition published in 1951 in English and held by 3 WorldCat member libraries worldwide

An investigation was conducted to determine the effects of a number of solution and aging treatments on the life of small cast gas-turbine blades of Haynes Stellite alloy 21 (a cobalt-chromium-base alloy). Solution treating at 2250 degrees F followed by slow furnace cooling and subsequent aging was found to improve the mean life an the initial failure time of the blades. The improvement was confirmed by statistical analysis. Metallographic examination revealed the presence of a lamellar structure in the improved blades. Other treatments investigated did not improve blade life. The blades were operated at 1500 degrees F and 20,000 pounds per square inch at the blade mid-span. Samples of 20 and 22 blades were used

Elevated-temperature combined stress-rupture plus fatigue strength of Waspaloy having different aging treatments and/or molybdenum contents by C. A Hoffman( Book )

1 edition published in 1958 in English and held by 2 WorldCat member libraries worldwide

A investigation was conducted to determine if the combined stress-rupture plus fatigue strengths of three groups of Waspaloy with different aging treatments and/or molybdenum contents could be correlated with their resultant stress-rupture ductilities and notch-rupture strengths
