Effect of heat treatment on stability of adiabatic shear bands in 4340 steelBoakye -Yiadom, Solomon 19 January 2011 (has links)
The fingerprint of deformation in materials at large strains and at high strain rates is the formation of adiabatic shear bands. Adiabatic shear bands lead to unexpected failure of materials during service. This study investigated the possibility of eliminating adiabatic shear bands from materials subjected to severe deformation at high strain rates by post impact heat treatment.
Five groups of cylindrical AISI 4340 steel samples were impacted using the Direct Impact Hopkinson Pressure Bar (DIHPB) developed at the University of Manitoba.
Selected impacted samples with distinct transformed shear bands were soaked at 350⁰C to 850⁰C for periods ranging from 30 minutes to 4 hours to investigate how temperature and time affects the properties and structure of the shear bands.
Annealing the shear bands at 350⁰C resulted in an increase in hardness of the shear bands and the surrounding material outside the shear bands regardless of the heat treatment before impact, amount of deformation, and the time of annealing.
Significant decrease in hardness of the shear bands occurred after post impact annealing at 650⁰C for 30 minutes and 2 hours. Hardness of the shear bands reduced to the same level as that of the impacted material outside the shear bands. However, the initial path of the shear bands in the impacted steel samples could be traced through a “signature” left after the annealing.
Post-impact annealing of the steel samples at 750⁰C and 850⁰C resulted in a homogenous microstructure with no trace of the shear bands. The “signatures” which were used to trace the path of the shear bands in impacted samples annealed at 650⁰C disappeared and the hardness across the samples became uniform.
The observations from this study show that adiabatic shear bands in typical steel can be eliminated by annealing heat treatment. The temperature of annealing is the most critical parameter and the annealing should be performed above 650⁰C.

Gilla, dela och kommentera - ett sätt att stärka kundrelationer? : En studie om hur träningsverksamheter använder Facebook / Like, share and comment – a way to strengthen the customerrelationships? : A survey of how companies use Facebook.Mattsson, Jennifer, Nilsson, Frida January 2015 (has links)
Syftet: Syftet med denna uppsats är att undersöka hur företag på sinFacebooksida arbetar med värde, interaktion och teknik för attstärka de sociala banden och därmed relationerna till sina kunder. Metod: Metoden för denna uppsats är kvalitativ med en ansats avdeduktivt slag. Data samlades in genom semistruktureradeintervjuer med utvalda företag som har en Facebooksida.Slutsats: Företag arbetar idag till viss del med värde, interaktion och teknikutifrån vad teorin rekommenderar. Det finns inom alla tre områdenbåde likheter och skillnader mellan verklighet och teori. Denundersökta modellen syftar till att stärka relationerna men det råderdelade åsikter från de undersökta företagen huruvida de uppleveratt relationerna har stärkts genom deras närvaro på Facebook.
