Laboratory evidence of strength recovery of a healed fault: implications for a mechanism responsible for creating wide fault zones
On the Mechanical Pulverizing for Metals by a Specially Designed Eddy Mill
A special eddy mill, in which metals are crushed chiefly by shearing due to mutual friction was designed and the crushing experiment for various metals and alloys was performed, and many important results on following subjects were obtained ; 1. Relation between work amount for pulverizing and pulverizing time. 2. Relation between work amount for crushing and particle size of material. 3. Variation in the particle size distribution of mill product for the treating time. 4. Microphotographs of pulverized powders. 5. Oxidation of pulverized powder and temperature rise in pulverizing
On the Mechanical Disintegration of Metal by a Stamp Mill
A disintegration experiment was made on some metals of different property by using a stamp mill, which was especially designed by one of the authors for the present work. The relationships between the work and the time, the mechanical property and the size of the material, and between the particle size distribution of the disintegrated product and the disintegrating time, were studied. The microscopic observation was also carried out on the all of the products during disintegration. On the basis of the experimental results the disintegration process and mechanism were considered
