Thermal treatment of soft carbons leads to progressive graphitization. It is improbable in nature since it requires a high activation energy. Graphite formation is thus attributed to shear stresses caused by pressure and geothermal gradient as in high pressure-high temperature experiments. A thermal

Evidence implying crack velocities in KCI crystals an order of magnitude greater than the velocity of the fastest elastic wave has been obtained. Fracture was produced by irradiation with a giant impulse laser, and average crack propagation velocities of the order of 104 to 10 5 m/sec were inferred
Measurements of crack velocities in KC1 crystals an order of magnitude greater than the velocity of the fastest elastic wave are reported. Fracture was produced by irradiation with a giant impulse laser, and average crack propagation velocities of the order of 10 ~ to 105 m/sec were inferred from th
