WHY DO YOU NEED ANSWERS? JUST CURIOUS? OR DO YOU HAVE A SPECFIC PROBLEM?
How is related hardness metals with its structure, grain size and composition?
ALL OF THE ABOVE.
How can I modify the hardness of a metal?
PURE OR ELEMENTAL METALS WORK-HARDEN BY COLD WORKING (COLD MEANING BELOW THE RECRYSTALLIZATION TEMPERATURE). THE HARDNESS IS MODIFIED TO SOFTER BY ANNEALING. SOME METAL ALLOYS ARE SUSCEPTIBLE TO HARDENING BY HEAT TREATING. FOR EXAMPLE; QUENCH AND TEMPER AND SOME BY SOLUTION TREATING AND PRECIPITION HARDENING. AGAIN YOU WILL NEED TO DO SOME READING TO UNDERSTAND THESE TERMS.
How must the surface be to perform a hardness test?
SHOULD BE A RELATIVELY SMOOTH SURFACE BUT TYPICALLY NO PREP NEEDED EXCEPT IN SPECIAL CASES AS NOTED IN A RECENT THREAD RIGHT HERE.
