This contribution proposes an optimization of material flow by means of modernizing of forging lines - type induction furnace / crank forging press / trimming press. The basis of design of forging line treatment is placement of hydraulic shear machine for shearing of heated bar to semi-products before respective forging of forged pieces. This method helped to remove previous redundant workplace for semi-products preparation, which causes reduction of technologic operations and substantial decrease of material flow in die forge. Proposed variant of material flow optimization brings economic profit by means of reduction of production times and fuels costs intended for pallets transport. Given save will be interesting for die forges as it contains also calculation of logistical effect.
The joining of Ti and Ni at low temperatures was analysed in this work. For joining pure Ti and Ni coins of 1.5 mm in thickness were used. Reactive multilayer thin films/foils with nanometric period (bilayer thickness), in particular Ni/Al multilayers, have been used to promote joining in two thickness of 28 and 55 nm. The ultrasonic soldering with SnAgTi active solder has been used for “hard-to-solder” material. The structural evaluation of soldered joint was studied by optical microscopy and EDX analysis. The structural analysis was focused to the creation of intermetallic layers in the joint interface. The mechanical properties of solder joints were tested by shear strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
