The behavior of die lubricant during casting in a diecasting process has not been fully investigated. Small amounts of HCl solution of radioactive H/sub 3/PO/sub 4/ were added to the die lubricant mechanically, and the radiographs of the surface and the inner part of the casting were taken after solidification. Comparatively large amounts of radioactive lubricant were applied. Zinc alloy ZAC No. 1 was cast in the dies. The results obtained were as follows: (1) The lubricant travelled with the flow front of the molten metal through the die cavity and accumulated at the place where the movement of molten metal came to end or remarkable turbulent motion occurred. (2) A large amount of lubricant was entrapped in the casting and distributed comparatively uniformly. (3) The chilled layer of casting occluded hardly any particles of the lubricant. (4) The entrapping of lubri cant increased with the rise of casting temperature and with the increase of gate area. (auth)
