Abstract: It has been found that ferromagnetic sheet material can be scribed in order to reduce watt losses by a thermal method involving rapid heating of small areas or narrow bands of the material in a manner that produces sudden thermal expansion to a degree sufficient to produce plastic deformation within the thermally treated zone. This method has been found to be particularly applicable to electrically insulative coated ferromagnetic sheet wherein it has been found that a laser operating in a continuous wave or extended pulse mode can produce the desired deformation in the ferromagnetic material without damage to the coating properties.

Abstract: This invention is of a process and an intermediate alloy for making an oriented-low-alloy iron (primarily recrystallized) which obtains maximum (110) [001] texture and improved magnetic properties by controlling the sulfur, carbon, manganese, and oxygen contents in the intermediate alloy to certain critical narrow ranges. With alloys containing the 0.01-0.15 percent manganese normally found in commercially available iron, the optimum intermediate (prior to final anneal) sulfur level has been found to be 0.004-0.008 percent. This sulfur level is appropriate for such manganese contents for a wide variety of silicon and chromium content. Similarly an intermediate carbon level of between 0.002 and 0.020% has been shown to give the maximum texture and best properties. The oxygen level must be 0.005 percent or lower and should be held as low as practicable. With these levels of sulfur, carbon, manganese, and oxygen, the alloy can be processed by hot rolling at 900.degree.-1200.degree. C. (usually between 1000.degree.-1100.degree. C.), followed by either two or three cold rolling stages with the final cold rolling providing a 50-75 percent reduction, and with annealing at between 750.degree. C. and the A.sub.Cl temperature of the material between cold rollings. The alloy can also contain 0-3% cobalt and up to total of 2% chromium and silicon.

Abstract: This is a low-alloy iron having desirable magnetic characteristics suitable for electrical applications such as transformer cores. This material has improved texture and reduced core losses. The alloys contain 0.6-1.0% silicon and 0.4-0.8% chromium along with controlled levels of manganese, sulfur, carbon and oxygen. These alloys are preferably processed to about 0.006 inch (0.015 cm) final gauge using schedules with three coldrolling steps. B.sub.10 values above 19 kG and 17 kG losses below 0.72 watts per pound are obtained with these alloys.

Abstract: A hard protective material and method for forming the medium having the formula C.sub.x N.sub.y. The medium may be formed as a protective film on a magnetic recording disk in a sputtering apparatus such as a magnetron apparatus. The amount of nitrogen in the film may be affected by controlling the collisions of the sputtered material between the target and deposition substrate by controlling the bombardment of the substrate by electrons. The films exhibit properties indicative of a textured morphology on a nanoscale which enhances the retention of lubricant overcoats.
