<PICT:0985247/C6-C7/1> <PICT:0985247/C6-C7/2> Articles to be heat-treated are immersed in a fluidized bed while surrounded by a static atmosphere, which may be inert or reactive to the object, or may be a vacuum. As illustrated in Fig. 1, article 1 is suspended from gantry 25 in vessel 3, which is mounted on a vibratory mechanism 3 so that material 9 forms a fluidized bed, while in the modification of Fig. 2, the bed is fluidized by vibration of the flexible base 7 of the vessel 31. Chamber 3 is heated by resistance heater 21, while loading chamber 23 is cooled by coil 33.
