Method for making steel with carbides already in the steel using material removal and deformation

A method of making steel having carbide banding, comprising the steps of:

• a. obtaining steel with undissolved carbides distributed within the steel for forming steel with carbide banding, wherein the steel comprises:
• i. from about 0.3 weight percent to about 2.2 weight percent carbon;
• and
• ii. at least about 0.003 weight percent of a metal selected from the group consisting of chromium, molybdenum, aluminum, vanadium, or tungsten;
• b. deforming the steel with undissolved carbides;
• c. removing a portion of the steel with undissolved carbides in a defined pattern selected from the group consisting of:
• a medieval pattern, decorative Celtic pattern, and an art deco pattern;
• d. heating the steel with undissolved carbides for a time less than about 5 minutes at a temperature above an A-sub 3 temperature to form an austenitic steel with undissolved carbides;
• and
• e. cooling the austenitic steel with undissolved carbides to maintain the undissolved carbides within a chosen crystalline matrix creating carbide banding in the steel.

A method of making steel with carbide banding, comprising the steps of:

• a. obtaining steel without dissolved carbides, wherein the steel comprises:
• i. from about 0.3 weight percent to about 2.2 weight percent carbon;
• and
• ii. at least about 0.003 weight percent of a metal selected from the group consisting of chromium, molybdenum, aluminum, vanadium, or tungsten;
• b. forming carbides in the steel by heating the steel without dissolved carbides at a temperature in the range from about an A-sub 1 temperature to about 50 degrees Fahrenheit above an A-sub 3 temperature to form an austenitic steel with undissolved carbides;
• c. deforming the austenitic steel with undissolved carbides;
• d. removing a portion of the austenitic steel with undissolved carbides;
• e. cooling the austenitic steel with undissolved carbides to precipitate carbides within a crystalline matrix forming a steel with carbide banding.

• and
• ii. at least about 0.003 weight percent of a metal selected from the group consisting of chromium, molybdenum, aluminum, vanadium, or tungsten;
• b. forming carbides in the steel by heating the steel without dissolved carbides at a temperature just below an A-sub 1 temperature to form an austenitic steel with undissolved carbides;
• c. holding the heated austenitic steel with undissolved carbides at the temperature just below the A-sub 1 for a time ranging from about 10 minutes to about 12 hours to form carbides in the steel;
• d. removing a portion of the austenitic steel with undissolved carbides;
• e. deforming the steel with formed carbides;
• and
• f. cooling the steel with formed carbides to precipitate the formed carbides within a crystalline matrix forming a steel with carbide banding.
