A METHOD OF MAKING A COMPOSITE METAL BODY SUITABLE FOR MAKING GAS TURBINE WHEEL BUCKETS AND THE LIKE AND CHARACTERIZED BY HIGH HOT STRENGTH AND RESISTANCE TO OXIDATION AT HIGH TEMPERATURES COMPRISING THE STEPS OF INTERLEAVING THIN SHEETS OF MOLYBDENUM WITH THIN SHEETS OF A NICKEL CHROMIUM ALLOY, THE MOLYBDEUM SHEETS HAVING A THICKNESS AT LEAST TWICE THE THICKNESS OF THE NICKEL CHROMIUM ALLOY SHEETS, THE SSTACK OF INTERLEAVED SHEETS BEGINNING AND ENDING WITH A NICKEL CHROMIUM SHEET, HEATING THE STACK OF INTERLEAVED SHEETS TO A TEMPERATURE OF THE ORDER OF 2200*F. IN A REDUCING ATMOSPHERE, AND WHILE SO HEATED APPLYING SUFFICIENT PRESSURE NORMAL TO THE STACKED SHEETS TO REDUCE THE STACK THICKNESS BY THE ORDER OF TWENTY PERCENT OF THE ORIGINAL THICKNESS WHEREBY THE METAL SHEETS WILL BECOME DIFFUSION WELDED TO FORM A COMPOSITE BODY CAPABLE OF BEING EMPLOYED AS FORGING STOCK AND FOR HOT ROLLED SHEET.
