Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article delves into the surface modification of Zr–Nb alloy through nanosecond pulse laser processing, a method aimed at enhancing the mechanical properties and fatigue resistance of the material. The study focuses on the impact of laser processing on the structure and hardness of the near-surface layer, revealing significant improvements in microhardness and residual compressive stresses. The results indicate that laser processing can create a microrelief on the surface, which is beneficial for biocompatible materials. The research also compares the effects of laser processing on fine-grained and ultramicrocrystalline specimens, highlighting the potential for substantial enhancements in the alloy's resistance to fatigue failure. The detailed analysis and comparison of different structural states provide valuable insights into the practical applications of laser processing in various industries.
