The detection of artificial reflectors and defect detection in mono- and polycrystalline samples made of heat-resistant nickel-based alloys are considered. The ultrasonic testing specificity of monocrystalline products is also considered. Defect detection in a turbine blade is carried out using an angle...
sealing bead (108), comprising a material portion (116) including intermetallic compounds of phase made of brazing metal e.g. tin, and another metal e.g. nickel or copper, where a fusion point of the latter metal is greater than that of the brazing metal. The connection element has ...
The vast majority of cultural heritage objects consist of materials that can be subjected to biodeterioration. Currently, there is significant number of publications showing which materials are capable of destroying certain organisms, and what conservation and restoration procedures are required. However, t...

Scientists say the object was made of the metals iron and nickel. It was about forty-five meters across and weighed several thousand tons. VOICE TWO: The rock from space that created the Barringer Crater hit the Earth with the force of about twenty-million tons of ...
A penny is 5 and a nickel is worth five cents, a dime is worth ten cents, 6 a quarter is worth twenty-five cents. You can use these coins to buy things at stores 7 to make change. Coins have been used as money for a long time. In the past, people used coins 8 (make) of ...
Although chemical analysis of copper alloys of cultural value indicates a wide variety of nickel contents in the range of less than0.01% up to 5%, nickel contents of object-groups originating from certain areas and times lie within relatively small limits. This finding helps to classify objects ...
