       M k Y p   
       wherein: 
 M is a metal selected from one or more of the group consisting of Fe, Ni, Co, V and Cr;  
 Y represents one or more elements from the group consisting of P, B and C;  
 k represents atomic percent, and has a value of from about 70-85;  
 p represents atomic percent, and has a value of about 15-30;  
 
     
     
         5 . An amorphous metal alloy article having an articulated topographical definition wherein the amorphous metal alloy has a composition which may be represented by the formula: 
       M a Y b Z c   
       wherein: 
 M is a metal selected from one or more of the group consisting of Fe, Ni, Co, V and Cr;  
 Y represents one or more elements from the group consisting of P, B and C;  
 Z is one or more elements selected from the group Al, Si, Sn, Ge, In, Sb or Be;  
 a represents atomic percent and has a value of from about 60-90;  
 b represents atomic percent and has a value of from about 10-30;  
 c represents atomic percent and has a value of from about 0.1-15; and a+b+c=100.  
 
     
     
         6 . An abrasive article which comprises the amorphous metal alloy article having an articulated topographical definition according to  claim 1 .  
     
     
         7 . An abrasive article which comprises the amorphous metal alloy article having a plurality of an articulated topographical definition according to  claim 2 .
