| A method of thermomagnetically processing an aluminum alloy entails heat treating an aluminum alloy, and applying a high field strength magnetic field of at least about 2 Tesla to the aluminum alloy during the heat treating. The heat treating and the application of the high field strength magnetic field are carried out for a treatment time sufficient to achieve a predetermined standard strength of the aluminum alloy, and the treatment time is reduced by at least about 50% compared to heat treating the aluminum alloy without the magnetic field. | ||||||

| A peening device is provided with: peening impact pins that impact on a surface to be worked; a device main body that uses vibration to move the peening impact pins back and forth with respect to the surface to be worked; servo motors (22x, 22y) that adjust the inclination of the device main body with respect to the surface to be worked; laser displacement gauges (20A, 20B, 20C, 20D) that detect the device angle; and a vibration sensor (18) that detects the vibration state of the device main body. Furthermore, a control device (40) for the peening device controls the servo motors (22x, 22y) such that the vibration state detected by the vibration sensor (18) is a predetermined vibration state. Thus, the peening device carries out excellent peening by conforming to the surface to be worked, the shape of which changes from moment to moment because of the peening. | ||||||
| 103 | Stress relief of mechanically roughened cylinder bores for reduced cracking tendency | US15042208 | 2016-02-12 | US09863030B2 | 2018-01-09 | Yucong Wang; Martin S. Kramer |
| A method of treating the surface of an aluminum-based engine block cylinder bore that has been mechanically roughened.

| 105 | Surface contouring of a weld cap and adjacent base metal using ultrasonic impact treatment | US14235530 | 2012-07-30 | US09605328B2 | 2017-03-28 | David John Sharman; Samuel B. Abston, II; Taylor Hanes |
| A method for forming a smooth interface between a weld cap and an adjacent base metal utilizing ultrasonic impact treatment. The method improves the geometric profile of a weld while imparting a compressive residual stress layer on the weld metal and base metal thereby alleviating the tensile residual stresses imparted to the metals during welding. The contouring process does not remove material, as in grinding, but plastically deforms the surface being treated producing a densified surface, in turn providing a smooth weld cap and base metal surface finish without the loss of base or weld metal thickness. | ||||||

| Disclosed are methods and systems for controlling of the microstructures of a soldered, brazed, welded, plated, cast, or vapor deposited manufactured component. The systems typically use relatively weak magnetic fields of either constant or varying flux to affect material properties within a manufactured component, typically without modifying the alloy, or changing the chemical composition of materials or altering the time, temperature, or transformation parameters of a manufacturing process. Such systems and processes may be used with components consisting of only materials that are conventionally characterized as be uninfluenced by magnetic forces. | ||||||
