A.{Mr Adams} Rowbotham Esq., c/o Messrs. Rolls-Royce Ltd., Derby. Dear Mr. Rowbotham, With reference to valve spring breakages possibly due to operation at very low temperatures. If you have not already read them, the following papers might be of interest. 1. The Mechanical Properties of some Austenitic Stainless Steels at low Temperatures (down to -180°C.) by Colbeck, MacGilliviey & Manning, to the Institute of Mechanical Engineers, May 1933. 2. Mechanical Properties of Metals at Low Temperatures, Colbeck & MacGilliviey, Institute of Mechanical Engineers, November 1933. 3. The Effect of the Temperature of Liquid Hydrogen on the Tensile Properties of 41 Specimens of Metals, Sir Robert Hadfield, Royal Society, see Phil. Trans. 1933, Series A, Vol. 232, p.297. Yours sincerely, Frank. B. Halford | ||
