localized phase variances in composition and ordering the presence of two phases present as lamellae results in ductility along the planes of the lamellae this ductility may be measured as percent elongation the following examples set forth preferred materials and methods for use in making the disclosed alloys these examples teach by way of illustration not by limitation and should not be interpreted as unduly narrow preparation and characterization of fe 30 ni 20 mn 35 al 15 a quaternary alloy of fe 30 ni 20 mn 35 al 15 composition was prepared by well known arc melting and casting techniques a quantity of material including 24 g fe 17 g ni 27 g mn and 5 g al was placed in a water cooled copper mold and heated until molten using the arc melting technique ingots were flipped and melted a minimum of three times under argon to ensure mixing quenching was done by allowing the alloy to rapidly cool in the copper mold to a temperature of u02dc 30 u00b0 c in approximately 10 minutes a eutectic transformation was carried out by holding the quenched ingots at about 1215 u00b0 c for about 30 minutes for this composition the eutectic transformation temperature as shown in the differential thermal analysis curve was between about 1210 1290 u00b0 c or between about 1212 1250 u00b0 c or between about 1214 1230 u00b0 c in some embodiments a 5 excess of mn may be added to the starting materials because mn accounts for the majority of weight loss during casting which results from brittle.
