Title: **Innovative Contributions of Karlfried Pfeifenbring to Metal Processing**
Introduction
Karlfried Pfeifenbring, an accomplished inventor based in Duisburg, Germany, has made significant strides in the field of metal processing. With a total of four patents to his name, he has focused predominantly on methods that enhance the properties and usability of cold-rolled strips, particularly for the manufacturing of battery cans.
Latest Patents
Pfeifenbring's latest patents include methods that detail a heat treatment technique for cold-rolled strips with nickel and/or cobalt surface coatings. His innovative method involves the incorporation of non-metallic elements such as carbon and sulfur, and potentially iron, indium, palladium, gold, and/or bismuth. This method is particularly beneficial as it selects a heat treatment temperature that is lower than the recrystallization temperature but higher than the precipitation temperature, ensuring optimal embrittlement of the grain boundaries. The resultant properties of the cold-rolled strips not only make them ideal for battery can production but also enhance their overall integrity. Another notable patent involves producing an improved cold-rolled strip that is suitable for deep-drawing or ironing and aims to maintain a low carbon content, thus reducing the tendency to form defects during processing.
