Studies were made on the nitrogen absorption of 20%Cr-Fe alloys containing aluminium up to 4% during heating at high temperatures in pure nitrogen or in air. The results obtained were as follows: (1) As the aluminium content of 20%Cr-Fe alloys was increased, more nitrogen was absorbed during heating in pure nitrogen. (2) When alloys containing aluminum were heated in pure nitrogen, the absorbed nitrogen combines preferentially with aluminium in alloys as AlN. Nitrogen-bearing austenite is not formed until aluminium is consumed as AlN. (3) When nitrogen is absorbed into the alloys containing aluminium, the beneficial effect of it on the resistance to oxidation is significantly deteriorated, and the ductility of such alloys is also reduced considerably. (4) The oxide film preformed on the surface of alloys containing 4% or more aluminium appreciably inhibited the nitrogen absorption in pure nitrogen. (5) In alloys containing 4% or more of aluminium, little amount of nitrogen was absorbed by heating in air due to the formation of the tight film of aluminium oxide. However, in alloys of lower aluminium content, nitrogen was absorbed considerably during prolonged heating in air and the resistance to oxidation as well as to nitrogenization caused by virtue of alloyed aluminium became lost.
