A hydraulic press (see Figure 1) which was constructed for high pressure work in the liquid helium temperature region has been utilized to obtain compressive testing data as a function of temperature for hot rolled 1020 steel, a pure iron, and several stainless steels.1 The lower end of the press could be placed in baths of liquid helium or nitrogen, or by using a special cryostat, the temperature of the sample could be held as long as desired at any temperature between 4.2 K and room temperature. The set-up was more convenient when used as a dead-weight tester since the pressure in the low friction hydraulic head was determined directly by using a free piston gauge, and pressures were varied by changing the weights on the piston of the gauge. Changes in sample length were obtained from the motion of a hairline on the room temperature end of the press piston using a micrometer telescope. Corrections were applied for the stretch of the support members and for the friction in the hydraulic head.
